In week 10-14.7, prof. Olga Kychkyruk (Ivan Franko Zhytomyr State University) was the guest of the Faculty of Physics and Astronomy, as part of the Erasmus+ programme. Within her visit, Prof. Kychkyruk delivered the lectures on nanocomposits. She also presented Ivan Franko Zhytomyr State University, visited Laboratory of Material Engeneering and participated in the meetings with students of the Faculty. The collaboration with the University in Zhytomyr was initiated this year, and we hope it will be continued in the upcoming editions within the Erasmus program.
